Oxalis Plant Seeds: Guide to Storing, Sowing and Germination

Introduction

Oxalis plants are known for their vibrant and delicate flowers, making them a popular choice among gardeners. If you have an oxalis plant and want to propagate it, understanding how to store, sow, and germinate its seeds is essential. In this guide, we will provide you with all the information you need to successfully grow oxalis plants from seeds.

Storing Oxalis Plant Seeds

To store oxalis plant seeds, it is important to ensure that they are fully matured before harvesting. The seed pods of an oxalis plant will turn brown and brittle when they are ready to be collected. Gently twist or cut off the seed pods and allow them to dry for a few days.

Once the seed pods are dry, carefully open them to reveal the tiny seeds inside. Oxalis seeds are small and resemble miniature pebbles. Place the seeds in a dry envelope or airtight container, and store them in a cool and dark place. A refrigerator or a basement can be suitable storage locations, as long as the temperature remains constant.

Sowing Oxalis Plant Seeds

Before sowing oxalis plant seeds, it is important to prepare the soil properly. Oxalis plants prefer well-draining soil that is rich in organic matter. You can mix compost or well-rotted manure into the soil to improve its fertility.

To sow the seeds, fill a seed tray or small pots with the prepared soil mix. The trays or pots should have drainage holes at the bottom to prevent waterlogging. Moisten the soil lightly before sowing the seeds.

Carefully scatter the oxalis seeds over the surface of the soil. Since they are tiny, it is best to sprinkle them evenly rather than placing them individually. Lightly press the seeds into the soil, ensuring that they are in good contact with it.

Germinating Oxalis Plant Seeds

Oxalis seeds require specific conditions to germinate successfully. They need a period of cold stratification, which mimics the winter season, followed by warmth to encourage sprouting. To achieve this, the seeds can be subjected to a process known as “pre-chilling.”

To pre-chill the oxalis seeds, place the seed tray or pots in a plastic bag and seal it. Store the bag in the refrigerator for about 4-6 weeks. This cold stratification triggers the seed’s natural dormancy break, preparing them for germination.

After the pre-chilling period, remove the seeds from the refrigerator and place them in a warm location with a temperature of around 70°F (21°C). Keep the soil consistently moist but not waterlogged. Covering the tray or pots with a plastic dome or plastic wrap can help retain moisture.

Care and Maintenance

Once the oxalis plant seeds have germinated, they will start developing into small seedlings. At this stage, it is important to provide them with proper care and maintenance to ensure their healthy growth.

Light: Oxalis plants prefer bright but indirect sunlight. Place the seedlings near a window where they can receive filtered light throughout the day.
Watering: Keep the soil evenly moist but avoid overwatering, as it can lead to root rot. Water when the top inch of soil feels dry to the touch.
Temperature: Maintain a moderate temperature range between 60-75°F (15-24°C). Avoid exposing the seedlings to extreme heat or cold.
Fertilizer: Once the seedlings have developed their second set of true leaves, you can start applying a balanced liquid fertilizer at half strength every two weeks.
Transplanting: When the seedlings have grown larger and have multiple sets of leaves, they can be transplanted into larger pots or directly into the garden. Ensure that the soil in the new location is well-draining and rich in organic matter.

Conclusion

Growing oxalis plants from seeds can be a rewarding experience for any gardener. By following the steps outlined in this guide, you can successfully store, sow, and germinate oxalis plant seeds. Remember to provide the seedlings with proper care and maintenance to ensure their healthy growth. With patience and attention, you will soon be enjoying the vibrant blooms of your own oxalis plants.
